At the conclusion

At the conclusion of the Irish War of Independence, the Anglo-Irish Treaty established the Irish Free State on 6 December 1922 as a self-governing dominion within the British Commonwealth.[note 2] It gained increasing sovereignty through the Statute of Westminster and the abdication crisis of 1936.[note 3] A new constitution introduced in 1937 declared it an entirely sovereign state named Ireland.[9][10] The last formal link with the United Kingdom was severed in 1949 when the Oireachtas (national parliament) passed the Republic of Ireland Act,[11] which proclaimed Ireland a republic by discarding the remaining duties of the monarch.[12] Ireland seceded from the British Commonwealth, having discontinued attending meetings in 1937.[13] Britain officially recognised the new republic through the Ireland Act 1949.
